Very earliest buses

Just wondering what time the earliest bus runs... we'd like to be there as early as possible for rope drop - especially the first day at MK... it opens at nine and we'd like to get there at least an hour early just to take it all in.

Also have Tusker House at 8 a.m. a day AK opens at 9.Boma at AKL for 8 a.m.... should we spring for a cab for this one? Cost estimate?Chef Mickey's breakfast at 7:30 at CR... cab better? $?And Crystal Palace at 8 a.m... same time MK opens - how early should we try to get there?
